The product is Didodecyl dimethyl ammonium chloride with the CAS number 3401 - 74 - 9. It is factory - supplied and comes with a low price. Didodecyl dimethyl ammonium chloride is a quaternary ammonium compound.
It usually appears as a colorless to pale yellow liquid. The molecular formula of Didodecyl dimethyl ammonium chloride is C₂₆H₅₆ClN, and its molecular weight is approximately 418.2 g/mol. It has good solubility in water and common organic solvents, and its pH value in aqueous solution is usually around 6 - 8, which shows relatively good chemical stability under normal conditions.
1. Antibacterial and Antifungal Agent: Didodecyl dimethyl ammonium chloride has strong antibacterial and antifungal properties. It can be used in the disinfection of various surfaces, such as floors, walls, and workbenches in hospitals, laboratories, and food processing plants. It can effectively kill a variety of bacteria, fungi, and some viruses, helping to maintain a clean and hygienic environment.
2. Textile Industry: It can be used as a fabric softener and antistatic agent. When added to the textile finishing process, it can make the fabric feel softer, more comfortable to wear, and reduce static electricity, which is beneficial to the production and use of textiles.
3. Water Treatment: In water treatment, it can be used as a coagulant and disinfectant. It can help to remove impurities and microorganisms in water, improve water quality, and is suitable for the treatment of industrial wastewater and domestic sewage.
1. Surface Disinfection: Dilute the product according to the recommended concentration. Usually, for general surface disinfection, a dilution ratio of 1:500 - 1:1000 can be used. Then, use a clean cloth or sprayer to apply the diluted solution to the surface to be disinfected. Let it stand for a certain period (usually 10 - 15 minutes) to ensure effective disinfection.
2. Textile Finishing: Add an appropriate amount of Didodecyl dimethyl ammonium chloride to the textile finishing bath. The specific dosage depends on the type and quantity of textiles. After adding, stir evenly and let the textiles soak for a period of time to ensure full adsorption.
3. Water Treatment: For water treatment, determine the appropriate dosage according to the water quality and treatment requirements. Add the product to the water treatment system and mix well. Usually, continuous or intermittent dosing can be used according to the actual situation.
1. Hospital Surface Disinfection: A large - scale hospital in the city used Didodecyl dimethyl ammonium chloride for surface disinfection. They diluted the product at a ratio of 1:800 and used sprayers to disinfect the wards, operating rooms, and corridors. After a period of use, the number of nosocomial infections decreased significantly, indicating that the product has excellent antibacterial and disinfection effects.
2. Textile Factory: A textile factory added Didodecyl dimethyl ammonium chloride to the finishing process of cotton fabrics. After the treatment, the fabric became softer, and the static electricity was greatly reduced. Customers reported that the wearing comfort of the products increased, and the sales volume also showed an upward trend.
3. Industrial Wastewater Treatment: An industrial plant used this product for wastewater treatment. They determined the dosage through water quality testing and added it to the wastewater treatment tank. After treatment, the suspended solids and microbial content in the wastewater decreased significantly, and the water quality met the discharge standards.
